Subject Re: org.apache.hadoop.util.PureJavaCrc32C not available
Date Tue, 23 Oct 2012 20:29:41 GMT
It's a tiny test cluster, with five nodes. Below, the configuration files:

First, Hadoop config. files
______________________________________________
core-site.xml
______________________________________________
<configuration>
<property>
<name>hadoop.tmp.dir</name>
 <value>/opt/hadoop/tmp</value>
</property>
<property>
 <name>fs.default.name</name>
<value>hdfs://master.cluster.org:54310/</value>
 </property>
</configuration>
______________________________________________
hdfs-site.xml
______________________________________________
<configuration>
<property>
<name>dfs.replication</name>
 <value>3</value>
</property>
</configuration>
______________________________________________
masters file
______________________________________________
master.cluster.org
______________________________________________
slaves file
______________________________________________
node1.cluster.org
node2.cluster.org
node3.cluster.org
node4.cluster.org

We're not using Hadoop's MapReduce, only HDFS.

Now, configuration files for HBase.
______________________________________________
hbase-site.xml
______________________________________________

<configuration>
<property>
 <name>hbase.zookeeper.quorum</name>
<value>master.cluster.org</value>
 </property>
<property>
 <name>hbase.zookeeper.property.dataDir</name>
<value>/opt/hbase/zookeeper</value>
 </property>
<property>
<name>hbase.rootdir</name>
 <value>hdfs://master.cluster.org:54310/hbase</value>
</property>
 <property>
<name>hbase.cluster.distributed</name>
<value>true</value>
 </property>
</configuration>
______________________________________________
regionservers
______________________________________________
node1.cluster.org
node2.cluster.org
node3.cluster.org
node4.cluster.org.

Thanks in advance!
